Application filed. May 28, 1915.

To all whomc't may concern Be it known that I, Crrns'rnn A. BARR, a citizen of the United States of America, residing at Portland, in the county of Multnomah and State of Oregon, have invented new and useful Improvements in Window- Ventilators, of which the following is a specification.

This invention relates to improvements in ventilators for use in the windows of buildings, cars, and other structures and in all places where ventilation is required, the object of the invention being to provide an in'mroved device of this character which is cheap and simple in construction, which may be readily attached to a window or other support, and which While admitting the free passage of air, prevents rain, snow and the like from entering through the ventilator and also prevents the entrance of flies and other insects.

The invention consists in the features of construction, combination, and arrangement of devices, hereinafter fully described and claimed.

In the accompanying drawings: Figure l is an elevation of a ventilator constructed and arranged in accordance with my invention,a portion of the body being removed and disclosing the segmental shutter and also disclosing a portion of the screen. Fig. 2 is an elevation showing the outer side of the ventilator and with a portion of the weather hood removed, to disclose a portion of the weather shutter. Fig. 3 is a vertical sectional view showing one end of the ventilator. Fig. 4 is a vertical sectional view taken on the plane indicated by the line 11 of Fig. 1.

The sash rail or other base H is provided with an oblong rectangular opening K, for the passage of air therethrough. A screen i of wire cloth or other suitable material is secured to the inner side of the sash rail, over said opening. The body A of the ventilator is semi-tubular and may be made of sheet metal or any other suitable material. The body has closed ends as at a and is also provided with outstanding side flanges a. Said flanges are provided with openings for the reception of screws wherewith the ventilator is secured to the inner side of the sash rail and arranged over the opening K as shown. The body of the ventilator is o provided with air inlet openings 7) in its Specification of Letters Patent.

upper side and is also provided in its upper side with a vertical slot 0 which is spaced mid-way between the ends of the body.

The ventilating shutter C, which is segmental in form is arranged in the body a and bears and fits against the inner side of the wall thereof. A knob Z) is secured to this shutter by a screw f and operates in the slot 0. By grasping this knob, the shutter C may be moved upwardly to close the opening I) and thereby cut ofi' the inlet of or may be lowered to uncover said openings.

A storm hood B is arranged on the outer side of the sash rail H over the opening K and has an upwardly extending flange g which is secured to the sash rail by screws as shown. A storm shutter E is arranged in the hood, is hingedly mounted at its upper edge as at j, and is connected by a rod D to the shutter C, said rod being connected to the shutter C as at e and having its outer end threaded, passed loosely through and opening in the storm shutter E, and provided with nuts h which are secured thereon and which are arranged on opposite sides of said shutter E as shown.

The storm shutter is thus connected to the ventilating shutter and when the latter is lowered, to uncover the opening Z), the shutter E is also moved to open position so that air can enter the room through the hood B, the opening K, the screen i, the chamber formed by the body of the ventilator A, and the opening 6.

It will be understood that the hood B effectually excludes rain and snow. When the shutter C is moved to closed position, the storm shutter E is also moved to closed position as will be understood.

Having thus described my invention, I claim:

1. In combination with a base having an opening, a ventilating device on the inner side of the base, and comprising a substantially semi-tubular body, covering said opening, closed at the ends, and having openings in its wall, a shutter mounted for movement on the wall to cover and uncover said openings, a hinged outer shutter mounted on the outer side of the body and a connection between said shutters to cause the outer shutter to be operated with and by the first named shutter.

2. In combination with a base having an opening, a ventilatingdevice on the inner side of the base, and comprising a sub-stantially semi-tubular body, covering said opening, closed at the ends, and having openings in its Wall, a shutter mounted for movement on the Wall to cover and uncover said openings, a hinged outer shutter mounted on the outer side of the body and aeonnection between said shutters to cause the outer shutter to be operated with and 13 by the first-named shutter, and an outer hood on the outer side of the base covering said opening, and to Which the upper side of the outer shutter is hingedly connected.
